YUCAIPA >> A portion of Highway 38 will be dedicated in memory of fallen San Bernardino County Sheriff’s Detective Jeremiah MacKay on Wednesday morning.

Sheriff John McMahon, 33rd District Assemblyman Tim Donnelly and other area dignitaries will unveil signs that will line two portions of the highway between mile markers 24 and 29 during a dedication ceremony planned at 10 a.m. at the Yucaipa Community Park Amphitheater, 3999 Oak Glen Road, said officials.

The ceremony will honor MacKay, who died Feb. 12 during a shootout with ex-Los Angeles police Officer Christopher Dorner.

He was 35.

Highway 138 led MacKay, who lived in Redlands, and other deputies to a fatal shootout with Dorner.

Deputy Alex Collins was injured in the incident, and has returned to his post with the department’s Big Bear Station.

Wednesday’s event will pay respects to MacKay’s memory and his heroism, said Donnelly.

“Too often we forget the incredible risk that those who have sworn an oath to protect and serve and put their lives on the line for our community take,” he said. “It’s a daily risk, and when you look at the incredible heroism of Jeremiah MacKay that day, he knew he was going into harm’s way, but he didn’t know he was going to pay with his life and leave young children without a father.

“It’s only fitting that we dedicate and consecrate the area where that sacrifice was made so that we never forget.”

The signs will be placed along the highway with one going up the mountain and one going down, said Cpl. Randy Naquin of the Sheriff’s Department.

The signs were paid for through the department’s Sheriff’s Employee Assistance Team, said Donnelly.

“This is definitely something we want to do to try and memorialize Jeremiah,” he said. “He was instrumental in what occurred, what happened on the mountain and prior to that particular incident. To be able to this for him and his family, it’s the least we can do.”
